Title: Intrusion detection system
Inventor: CORBELL PAUL IRVING
IPC: G08B13/24
Filed: 1965-05-05
Abstract: 1,102,276. Intruder alarms. JOHNSON SERVICE CO. 5 May, 1965, No. 19030/65. Heading G4N. [Also in Divisions H3 and H4] In an alarm system for detecting the presence of a moving body in an area utilizing the Doppler effect, an alarm signal is initiated only when the amplitude of the selected Doppler signal exceeds a predetermined value. After detection, the Doppler signal is fed via an amplifier 19 to a Schmitt trigger 21, 22 of which transistor 22 is normally off. When the Doppler signal exceeds a predetermined amplitude, the trigger circuit switches and relay 23 releases to initiate an alarm. In order to indicate that the equipment is functioning correctly, the received background signals are fed via an amplifier 32 to an integrator and rectifier 33 which produces a bias to hold transistor 34 conducting. Failure of the system allows transistor 34 to cut off and release relay 35 to give a " fault " alarm. In a modification, Fig. 3 (not shown), the fault alarm may comprise a single transistor 41, biased to be conducting, with its emittercollector path shunted by an alarm relay 35. The back-ground signals normally hold this transistor cut-off and the relay 35 is thus energized. Failure of the system results in the transistor 41 becoming conductive to release relay 35. The back-ground signal may be supplemented by a tone modulated on to the transmitted signal.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1949-07-20
Abstract: 664,209. Refrigerating. ELECTROLUX, Ltd. July 20, 1949 [July 22, 1948], No. 19087/49. Class 29 The absorber vessel 16 of a continuous cycle refrigerating system of the inert gas type is located within the heat insulation 11 of the boiler unit and receives heat from the expelled vapours and/or from the weak liquor flowing to the absorber coil 22. Strong liquor flows from the top of the vessel 16 down a boiler pipe 12 in heat exchange with the flue 10 to a pump tube 13 discharging into a pipe 14 which may be heated by the flue 10. Weak liquor flows from the pipe 14 through a coil 19 immersed in the absorber vessel 16 and then flows to the absorber 22 by a pipe 20. Strong liquor flows to the vessel 16 from the absorber by a pipe 21 which is in heat exchange with the pipe 20. Refrigerant vapours generated in the pipe 14 and the pump 13 flow downwardly through a pipe 15 leading into an inclined portion of the pipe 12 within the vessel 16. These vapours together with vapours generated in the pipe 12 are analyzed by bubbling through strong solution in this inclined portion into the top of the vessel 16 from which they flow through a rectifier 17 to a condenser 18. Mixed gases from the evaporator flow from the gas heat exchanger 25 through a conduit 26 to the foot of the coil 22 and inert gas flows from the top of the coil 22 to the gas heat exchanger through a pipe 24. A vessel 27 surrounds the conduit 26 and communicates therewith by an orifice 28 to form a pressure vessel. Liquid refrigerant drains from the condenser 18 into the pressure vessel and flows therefrom through a pipe 29 to a vertical pipe 31. This pipe 31 receives heat from the rectifier 17 and thus acts as a bubble pump to force liquid refrigerant to a sufficient height for supplying the evaporator system. Any vapours formed in the pump pipe 31 are condensed in an auxiliary condenser 32. Should absorption solution be present in the pressure vessel 27, the pump pipe 31 will not be hot enough to pump the diluted refrigerant and the solution in the vessel 27 will drain through a pipe 30 opening into the rectifier 17 at substantially the same height as the normal refrigerant level in the vessel 27. Unevaporated refrigerant drains from the gas heat exchanger through a pipe 33 to a vessel 35 in contact with the rectifier 17, the vapours from the rectifier returning to the condenser 18. The absorber vessel 16 may be a concentric member around the flue 10. The auxiliary condenser 32 may be dispensed with and a liquid seal included in the pipe feeding refrigerant to the evaporator system, Fig. 2 (not shown). Instead of the absorption solution drain pipe 30, a liquid seal draining from the pump pipe 31 into the rectifier 17 at substantially the same level as or rather higher than the normal refrigerant level in the pressure vessel 27 is described, Fig. 3 (not shown). Specification 664,208 is referred to.

Title: A method of breaking or disintegrating materials and a tool therefor
IPC: B25D17/24
Filed: 1959-06-05
Abstract: 910,754. Cartridge-operated tools. GROTSCH, G. June 5, 1959 [June 7, 1958; March 20, 1959], No. 19261/59. Class 119. A cartridge-operated tool for firing a bit or pin into solid materials such as concrete, brickwork and wood and which may be used for breaking or splitting such materials, comprises a barrel 1, Fig. 1, in which the enlarged integral or separate head 3 of a bit 2 is slidably guided, the head 3 being provided with a chamber 5 for a cartridge 5a and a hammer and slide assembly 16, 18 adapted to be thrust forward for effecting ignition of the cartridge and thereafter partly or wholly to absorb the recoil thrust of the powder gases. As shown in Fig. 1, the bit 2 and its head 3 are integral and free flight of the bit is prevented by a buffer 7 slidably disposed in the muzzle of the barrel and provided with a buffer spring 13 which absorbs the shock of impact when the head 3 strikes a shoulder 8 on the buffer. A rubber buffering element may be used instead of the spring 13. The buffer 7 is formed with an annular cutting edge 15 or serrated teeth. Alternatively, as shown in Fig. 3, the pinlike bit 46 and the head 3 are separate elements which are in loose contact via an extension 3a of the head, the buffer 7 retaining the head 3 but allowing free flight of the pin 46. Whereas in Fig. 1, the base 5b of the cartridge is openly exposed to the hammer 16 and its striker pin 24, the base 5b of the cartridge in Fig. 3 faces the direction of drive and the cartridge is located inside a holder 56 which is a slidable fit in a recess in the head 3. The hammer 16, Fig. 1, slides in the barrel 1 and is secured to the slide 18 by screw threads 17. The slide 18 is displaceable in a casing 25 provided with a butt 26 and a recoil spring 27 urges the slide against a locking ring 28 on the casing 25. For firing the casing 25 is held by the butt 26 and thrust forward against the pressure of the restoring spring 22. This movement entrains both slide 18 and hammer 16 and engages the striker 24 and cartridge. The inertial mass of the recoiling hammer and slide is several times greater than that of the bit so that the recoil thrust is absorbed by the spring 27. The tool shown in Fig. 3 is provided with a modified hammer and slide assembly and has a shatter guard comprising a shield 57 rotatably mounted on the barrel 1 and provided with a window 58, a cover-plate 59 being secured to the barrel and having a corresponding window 60. A torsion spring 61 urges rotation of the shield to bring the two windows out of alignment before firing. Alternatively, the shield may be a fixed member and the cover-plate arranged to rotate.

Abstract: 770,314. Machine-tool details; turning. HAHN, T. July 1, 1954 [July 7, 1953], No. 19324/54. Class 83 (3). In a machine-tool, eg. a lathe, a carriage 15, Fig. 1, is fed, e.g. by a lever 22 having a quadrant 20 engaging a rack 21, or by hydraulic means, at a speed governed by a screwed rod 11 driven from the work-spindle 6 via change-wheels 9, 10. Toothed-wheels 12, 13 in mesh with the rod are mounted in the carriage apron 14 and have fixed thereto discs 23, 24, each having one end 26 shaped to abut a spring-pressed stopplunger 28, and the other end 27 bevelled. Thus, when the carriage is fed towards the work, the wheels are held stationary by ends 26 engaging plunger 28 whereby the feed speed is limited. On retracting the carriage, the wheels rotate and ends 27 depress plunger 28. In another arrangement, for screw-cutting, toothedwheels 48, 52, Fig. 3, mesh with rod 11, and wheel 48 also meshes with a wheel 49 which is changed according to the pitch of the thread being cut to maintain small idle movement of the wheel when feeding up to the work. Disc 51 is fixed to wheel 49 and co-operates with stop 50 as previously described. Cross-slide 58 supporting the tool has a slot 57 engaging a pin 56 extending from a bar 54 slidable in the carriage parallel with the work axis. The bar is loaded by a spring 55 to co-operate with a stop 59 on the machine-frame and has a bore 64, Fig. 5, through which passes a pin 62 which threadedly engages a nut 68 rotated by a pawl 75, which abuts a stop 77 on the frame when the slide is retracted. At the end of the first cut, stop 59 retracts bar 54 which, through pin 56, removes the tool from the work and is held retracted by pin 72. When the slide is retracted, stop 77 causes the nut 68 to turn a predetermined amount to lower pin 62 which, by its sloping face 63, causes bar 54 to project further out of the carriage and moves pin 56 further up slot 57. Also a projection 81 raises pin 72 to release the bar which assumes its new position and advances the tool to take a deeper cut. The final cut is limited by a stop 61. The drive of rod 11 incorporates a pinion 42 free on shaft 43 and having a pin 46 engageable with any one of a number of slots 45 in a disc 44 keyed to said shaft, whereby multiple threads may be cut. Drilling; milling.-The feed arrangement may be incorporated in a milling-machine particularly for climb-milling, and in drilling- machines.

Abstract: 776,908. Catamenial tampons. SANITARY PRODUCTS CORPORATION. July 4, 1955, No. 19329/55. Class 81(2) The tip of a tampon is provided with a cap of prefabricated pliable material, such as a film, bonded to it. The film must be soluble in body fluids and suitable materials are methyl cellulose, hydroxyethyl cellulose sodium cellulose sulphate, carboxymethyl cellulose and polyvinyl alcohol. In a machine for applying the tip a strip of film F is gripped between members 10, 11, which are heated to make the film pliable, and the tampon T is driven downwards against the film to stretch it tightly over the tip. At the same time an annular cutter 15 moves upward to cut the film closely around the tampon and this' continues to move downward through tube 23 so that the film is pressed into close contact with it. The applied heat causes the film to adhere to the tampon material but, if desired, an adhesive coating may be applied to the tampon before the film is attached. The film preferably incorporates a plasticizer such as glycerine, sorbitol, polyethylene glycol or higher alcohol derivatives.
